161AY SERIES PILOT

IntroductionScope of ManualThis instruction manual provides installation, startup, adjustment, maintenance, and parts ordering information for the Type EZR pressure reducing regulator, the Type 112 restrictor, the 161AY Series pilot, the 161EB Series pilot, and the PRX Series pilot. Any accessories used with this regulator are covered in their respective instruction manuals.

Product DescriptionThe Type EZR pilot-operated, pressure reducing regulators are used for natural gas, air, or other

non-corrosive gas applications and include a Type 112 restrictor and a 161EB, 161AY or PRX Series pilot. For applications that have high pressure drops, using a Type 161AYM or 161EBM monitor pilot will increase the accuracy of the regulator.

SpecificationsSpecifications for the Type EZR regulator are found on page 2. The control spring range for the pilot is marked on the spring case of 161EB Series pilots and on the nameplate of 161AY and PRX Series pilots. Other information for the main valve appears on the nameplate.

Table 1. Main Valve Body Sizes, End Connection Styles, and Body Ratings

Principle of OperationAs long as the outlet (control) pressure is above the outlet pressure setting, the pilot valve plug or disk remains closed (Figure 2). Force from the main spring, in addition to inlet pressure bleeding through the Type 112 restrictor (the restrictor is integral in the PRX Series pilots), provides downward loading pressure to keep the main valve diaphragm and plug assembly tightly shutoff.

When the outlet pressure decreases below the pilot outlet pressure setting, the pilot plug or disk assembly opens. Loading pressure bleeds downstream through the pilot faster than it can be replaced through the Type 112 restrictor. This reduces loading pressure on top of the main valve diaphragm and plug assembly and lets the unbalanced force between inlet and loading pressure overcome the main spring force to open the Type EZR diaphragm and plug assembly.

Table 3. Pilot Pressure Ratings

As the outlet pressure rises toward the outlet pressure setting, it compresses the pilot diaphragm against the pilot control spring and lets the pilot valve plug or disk close. Loading pressure begins building on the Type EZR diaphragm and plug assembly. The loading pressure, along with force from the main spring, pushes the diaphragm and plug assembly onto the knife-edged seat, producing tight shutoff.

Pilot Type DescriptionsType 161AY—Low-pressure pilot with an outlet pressure range from 6-inches w.c. to 7 psig (15 mbar to 0,48 bar). Pilot bleeds (exhausts) downstream through the sense (control) line.

Type 161AYM—The monitor version of the Type 161AY pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).

Type 161EB—High accuracy pilot with an outlet pressure range from 5 to 350 psig (0,34 to 24,1 bar). Pilot bleeds (exhausts) downstream through the sense (control) line.

Type 161EBM—The monitor version of the Type 161EB pilot. The pilot bleed (exhaust) is isolated from the sense (control) line. This pilot is used in monitoring systems requiring an isolated pilot bleed (exhaust).

Type PRx/120—Outlet pressure range of 7.3 to 609 psig (0,5 to 42 bar). The Type PRX/120 can be used as the pilot on single-stage pressure reducing regulators or as the monitor pilot or as the working pilot in wide-open monitor systems. The Type PRX has a double diaphragm which provides increased accuracy and sensitivity, an integral restrictor adjustment to allow adjustable opening and closing speeds, and a damper adjustment to allow adjustments to make for inlet pressure variability and loading pressure oscillations.

Additionally, physical damage to the regulator could break the pilot off the main valve, causing personal injury and property damage due to escaping gas. To avoid such injury and damage, install the regulator in a safe location.

All InstallationsThe robust design of the Type EZR allows this regulator to be installed indoors or outdoors. When installed

outdoors, the Type EZR does not require protective housing. This regulator is designed to withstand the elements. The powder paint coating protects against minor impacts, abrasions, and corrosion. When installed indoors, no remote venting is required except on the pilot spring case. This regulator can also be installed in a pit that is subject to flooding by venting the pilot spring case above the maximum possible flood level so the pilot setting can be referenced at atmospheric pressure.

Before installation, make sure that regulator. Before installation, make sure thatregulator. Before installation, make sure that there is no damage to, or debris in, the regulator. Also, make sure that all tubing and piping are cleanAlso, make sure that all tubing and piping are clean and unobstructed.and unobstructed.

NoteThe Type EZR optional inlet strainer is intended to prevent occasional large particles from entering the main valve. If the gas contains continuous particles, upstream filtration is recommended. When using an inlet strainer (key 23), do not use the shim (key 23) and vise versa.

2. A Type EZR regulator may be installed in any orientation, as long as flow through the regulator matches the direction of the arrow on the main valve body. However, for easier maintenance, install the regulator with the bonnet up.

CAUTION

When installing a Type EZR trim package in an existing E-body, make sure flow is up through the center of the cage and down through the cage slots. In some cases, correct flow path is achieved by removing the body from the line and turning it around. If this is done, change the flow arrow to indicate the correct direction. Damage may result if flow is not in the correct direction. After assembly, check the regulator for shutoff and leakage to atmosphere.Types EZR/399 restricted trim bodies (6 x 4, 8 x 4, 8 x 6, 12 x 6-inch (DN 150 x 100, 200 x 100, 200 x 150, 300 x 150)) are different than EW valve bodies and are not interchangeable. Only install trims in correct restricted trim bodies.

3. The standard pilot mounting position is as shown in Figure 1. Other mounting positions are available. 4. Apply a good grade of pipe compound to the male pipeline threads for a screwed body, or use suitable line gaskets for a flanged body. When installing buttweld end connections, remove trim before welding and make sure to use approved welding practices. Use approved piping procedures when installing the regulator.

CAUTION

A regulator may vent some gas to the atmosphere. In hazardous or flammable gas service, vented gas may accumulate and cause personal injury, death, or property damage due to fire or explosion.

Pilot supply for the downstream monitoring regulator must be obtained between theregulator must be obtained between the two regulators as stwo regulators as shown in Figure 4. With this arrangement, the downstream monitoring regulator diaphragm changes position with every load change. For sizing purposes, add the minimum differential pressure for each regulator together to establish the required pressure drop across the station. System lockup pressure is equal to the setpoint of the working regulator pilot when a Type 161EBM or a Type 161AYM is used on an upstream regulator, otherwise lockup pressure is equal to monitor pilot lockup pressure.

Working Monitor InstallationsOn working monitor installations, the working monitor regulator is always upstrea� and acts as a first-stage regulator through the working pilot during normal operation. This arrangement allows the working monitor’s performance to be observed at all times. Then, should the second-stage regulator fail open, the working monitor regulator assumes the entire pressure reduction function of the system through the monitoring pilot.

Use the following procedure when installing a working monitor system.

Table 9 gives the spread between normal distribution pressure and the minimum pressure at which the monitor pilot can be set to take over if the working regulator fails open. 5. Table 4 shows the minimum differential pressure requirements across an individual regulator. Because this application uses a first-stage and second-stage pressure reduction, add the minimum differential pressure for each regulator together to establish the required pressure drop across the station. Do not exceed maximum pilot ratings given in Table 3.

Type EZR/PRx Working MonitorOn working monitor installations, the working monitor regulator is always upstrea� and acts as a first-stage regulator through the working pilot during normal operation. This arrangement allows the working monitor’s performance to be observed at all times. Then, should the second-stage regulator fail open, the working monitor regulator assumes the entire pressure reduction function of the system through the monitoring pilot. Use the following procedure when installing a working monitor system.

As shown in Figure 5, run a supply pressure line (use 3/8-inch (9,5 mm) outer diameter tubing or larger) from the upstream pipeline to the inlet (Port S) of the upstream Type PRX-120 pilot. Install a Type 252 pilot supply filter upstrea� of the pilot, if needed, to keep the supply source from clogging the restrictor in the pilot. Inspect and clean this filter regularly to �ake sure it has not been plugged.

The pilot supply pressure connection for the downstream Type EZR regulator must be directly upstream of the Type EZR using intermediate pressure and connected to the “S” port of the downstream Type PRX-120. Install a Type 2�2 pilot supply filter upstream of the pilot, if needed, to keep the supply source from clogging the restrictor in the pilot. Inspect and clean this filter regularly to �ake sure it has not been plugged. Connect the loading port (Port L) of the downstream Type PRX-120 pilot to the bonnet of the downstream Type EZR regulator. Connect the “A” and “B” ports of the downstream Type PRX-120 pilot to downstream pressure.Significant restrictions in control lines can prevent proper pressure registration. Connect the control line a minimum of 8 to 10 pipe diameters downstream of the regulator in a straight run of pipe. Do not make the control line connection in a turbulent area, such as in or directly downstream of a swage or elbow. When used, a hand valve should be a full flow valve such as full port ball valve.Table 4 shows the minimum differential pressure requirements across an individual regulator. Because this application uses a first-stage and second-stage pressure reduction, add the minimum differential pressure for each regulator together to establish the required pressure drop across the station. Do not exceed maximum pilot ratings given in Table 3.

Startup and Adjustment Note

Table 10 show maximum inlet and differential pressures for specific constructions. Use pressure gauges to monitor inlet pressure, outlet pressure, and any intermediate pressure during startup.

CAUTION

To prevent damage to the Type PRx pilot during startup, the sense and bleed lines of the Type PRx should be located on the same side of the downstream block valve.

Startup for Both Single-Regulator and Monitoring Installations 1. Make sure all block and vent valves are closed. 2. Back out the pilot adjusting screw(s). 3. For easy initial startup, set the restrictor to the “8” position. For future startups, the restrictor can be left in the desired run position.

4. SLOWLY OPEN the valves in the following order: a. Pilot supply and control line valve(s), if used b. Inlet block valve c. Outlet block valve

5. For a 161 Series pilot with Type 112 restrictor, turn the restrictor(s) to position “2” or to the desired run position. For a PRX Series pilot, turn the restrictor screw 1 turn counterclockwise from fully seated (turn restrictor fully clockwise then 1 turn counterclockwise) and the damper screw fully counterclockwise.

6. For a single regulator, set the pilot to the desired outlet (control) pressure according to the pilot adjustment procedure.

For a wide-open downstream monitor installation, adjust the upstream working pilot until intermediate pressure is higher than the desired setpoint of the monitor pilot. Adjust the downstream monitoring pilot to the desired monitoring takeover pressure. Reduce the upstream pilot to the normal outlet pressure setting. For a wide-open upstream monitor installation, adjust the downstream working pilot to a setpoint higher than the setpoint of the monitor pilot. Adjust the upstream monitoring pilot to the desired monitor takeover pressure. Reduce the downstream pilot setting to normal outlet pressure setting. For a working monitor installation, adjust the setpoint of the upstream monitor pilot to the desired maximum pressure. Adjust the upstream working pilot to the desired intermediate pressure setting. Adjust the downstream pilot to a pressure setting slightly above the upstream monitor pilot pressure setting. Adjust the upstream monitor pilot to its desired setpoint. The setpoint of the monitor pilot should be adjusted at least to the guidelines shown in Table 9. The maximum may be greater. Then, establish final desired downstrea� pressure by adjusting the downstream working regulator pilot.

Pilot AdjustmentFor 161 Series pilots, remove the pilot closing cap (key 16, Figure 19 or key 22, Figure 20) and, on 161EB Series only, loosen the locknut (key 12, Figure 19). Turn the adjusting screw (key 11, Figure 19 or key 35, Figure 20) into the spring case (key 2, Figure 19 or key 3, Figure 20) to increase the downstream pressure. Turn the adjusting screw out of the spring case to decrease the downstream pressure.

For PRx Series pilots (Figure 27), loosen locknut (key 2) and turn the adjusting screw into the spring case to increase (or out of the spring case to decrease) the downstream pressure. When the required downstream pressure is maintained for several minutes, tighten the locknut to lock the adjusting screw in position (161EB Series only) and replace the pilot closing cap.The Damper and Restrictor screws on the PRX Series pilot control the regulator’s proportional band (droop) and speed of response. Table 7 includes the appropriate settings for low flow operation. For additional tuning follow the steps outlined below: 1. Start with the restrictor screw 1 turn counterclockwise from fully seated (turn restrictor fully clockwise then 1 turn counterclockwise) and the damper screw fully counterclockwise. 2. Turn damper screw clockwise until desired perfor�ance is achieved. This reduces the flow path of the damper. If the damper becomes fully seated (no longer able to turn clockwise) and the desired performance has not been achieved, return the damper screw to the fully counterclockwise position.

! WARNING

The damper screw should not be left in the fully seated position, as it will lock the regulator in last position which could cause incorrect pressure regulation.

3. Turn the restrictor screw an additional turn counterclockwise from fully seated. This increases the flow path of the restrictor. If additional tuning is required, repeat step 2. Follow this method until desired performance is achieved.

Type 112 Restrictor AdjustmentThe Type 112 restrictor controls the regulator’s proportional band (droop) and speed of response. The restrictor can be used to fine tune the regulator for maximum performance by decreasing the restrictor setting for tighter control (increased opening speed, decreased closing speed); or increasing the restrictor setting for maximum stability (decreased opening speed, increased closing speed). A lower setting also provides a narrower proportional band for better accuracy. The “8” position has the largest flow, is most stable, and easiest for startup, however, using the “8” position is not necessary. The “0” setting has the s�allest (�ini�u�� flow passage; at no point of rotation will the Type 112 restrictor be completely shutoff. After initial adjustment, the restrictor does not need to be adjusted for maintenance or startup.

Pilot Adjustment – (For Low Flow Applications Only) For stable, low-flow operation, other considerations besides pilot settings should also be addressed. Installation of an over-sized regulator may make low-flow operation difficult. When possible, a smaller-sized Type EZR should be installed. During design of a regulator installation, the downstream piping volume should be maximized. Control lines should not be located in or near piping sections that may experience turbulent flow, such as elbows or swages. Larger diameter control lines are also recommended in low-flow conditions. The larger control lines are less restrictive and will reduce pilot exhaust bleed backpressure to the pilot that may cause instability. Separate sense and exhaust lines may also help at low flow conditions. This feature is provided on the PRX Series, Types 161M, 161HM, 161EBM, and 161AYM pilots. Control line taps should be located in straight pipe; several pipeline diameters (8 to 10 of largest piping on outlet) downstream of the regulator. These guidelines are not mandatory but have been used to improve station stability at low flow in some systems.

If pilot supply pressure is shutdown first, the downstream system may be subjected to full inlet pressure.

Open the vent valves to depressurize the system.

MaintenanceRegulator parts are subject to normal wear and must be inspected periodically and replaced as necessary. Due to the care Fisher takes in meeting all manufacturing requirements (heat treating,

dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Fisher. Also, when lubrication is required, use a good quality lubricant and sparingly coat the recommended part. The frequency of inspection and parts replacement depends upon the severity of service conditions, applicable codes and government regulations, and company inspection procedures. Table 12 lists various regulator problems and possible solutions for them.

CAUTION

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled gas or other process fluid. Before starting to disassemble, carefully release all pressures according to the shutdown procedure. Use gauges to monitor inlet and outlet pressures while releasing these pressures.

Converting a Fisher E-Body to Type EZR:Remove all trim parts from the main valve and clean the body interior. Then follow procedure in Assembly section to convert a Fisher E-body to a Type EZR.

CAUTION

When installing a Type EZR trim package make sure flow is up through the center of the cage and down through the cage slots. In some cases, correct flow path is achieved by removing the body from the line and turning it around. If this is done, change the flow arrow to indicate the correct direction. Damage may result if flow is not in the correct direction. After assembly, check the regulator for shutoff and leakage to atmosphere.

DisassemblyDisassembly of Type EZR: 1. Shut down, isolate, and depressurize the main valve and pilot.

2. Remove the cap screws (key 3). Lift up and remove the bonnet (key 2) from the body (key 1).

3. Remove the diaphragm and plug assembly (key 9) and bonnet O-ring (key 28). For 2 x 1-inch (DN 50 x 25) sizes, use a screwdriver to remove the upper adapter (key 131).

4. Pull out the cage (key 7), O-ring (key 8), and inlet strainer or strainer shim (key 23) (if no strainer). For 2 x 1-inch (DN 50 x 25) sizes, remove the lower adapter (key 132).

5. Clean parts and replace if necessary. To change the O-ring (key 121) on a 6-inch (152 mm) cage with attached restrictor plate (key 71), remove cap screws (key 126).

Assembly 1. Install the inlet strainer or shim (key 23) into the body (key 1).

Note

When installing in a vertical orientation, apply lubricant to the bottom of the inlet strainer or strainer shim (key 23) to help hold parts in place while installing cage.

Lubricate the top and bottom of the outer edge (bead area) of the diaphragm and place diaphragm and plug assembly (key 9) on the cage (key 7). For 2 x 1-inch (DN 50 x 25) sizes, the upper adapter (key 131) must be placed on the cage before the bonnet (key 2). Lightly lubricate the upper adapter O-ring (key 133) and then press the upper adapter onto the cage. 6. If travel indicator was removed, lightly lubricate the travel indicator assembly threads and screw it into the bonnet (key 2). See Travel Indicator Assembly Maintenance for maintenance. 7. Install the bonnet (key 2) in proper orientation.

CAUTION

Make sure to use a Type EZR bonnet. The Type EZR bonnet is NOT interchangeable with other Fisher E-body bonnets. Installing an improper bonnet can result in stem assembly

breakage and unit failure. The bonnet can be identified by the Type EZR markings on the top.

8. Lubricate cap screws (key 3) and secure the bonnet (key 2), using an even crisscross pattern. It may be necessary to push down on bonnet to start cap screws. Tighten cap screws to proper torque (see Table 13).

Diaphragm and Plug Assembly MaintenanceThe diaphragm and plug assembly can be replaced as a single unit (a diaphragm cartridge), or individual components within the assembly can be replaced. When replacing individual components, inspect each component for damage and wear, and replace parts as needed. Key numbers for the following assembly and disassembly procedure are referenced in Figures 9 and 14. 1. Place a screwdriver or similar tool through the hole in the top plug (key 5). 2. Re�ove the flanged locknut (key 13� fro� the bottom plug (key 11). This loosens the entire assembly.

PROBLEM POSSIBLE SOLUTION Outlet pressure suddenly rises above setpoint and approaches inlet pressure

• If travel indicator is in UP position, check restrictor and pilot supply filter for plugging • If travel indicator is in DOWN position, check main valve for debris or diaphragm damage

Outlet pressure nor�al at low flow but falls below setpoint at high flow

• Check main valve inlet strainer for plugging • Check inlet pressure at high flow condition • Check sizing calculations to be sure main valve body is large enough for load • Check for undersized or restricted control line (use the minimum size given in step 6 of All Installations of the Type EZR Installation section.) • Adjust restrictor to a lower setting

Outlet pressure cycles • Adjust restrictor to a higher setting • Check control line placement. Make sure it is not located in a turbulent area. • Make sure there is not a restriction in the control line, such as a needle valve.

Gas escapes from pilot spring case • Replace pilot diaphragm assembly Gas escapes from travel indicator • Replace indicator stem O-ring, if indicator is not desired, convert to a non-travel indicator assembly

Regulator unexpectedly closes or falls below setpoint

• Check pilot for ice. Moisture in the gas can cause ice to for� and build up in the pilot, blocking the flow. This most commonly occurs when ambient temperature is 30° to 40°F (-1° to 4°C). Heating the regulator or adding a de-icing agent will reduce the possibility of icing.

Outlet pressure approaches inlet pressure when no flow is desired

• Check main valve O-rings for damage or improper installation • Check cage and diaphragm surfaces for erosion or trapped debris • Check pilot valve plug and seat for seating surface damage or debris • Check pilot for ice

Regulator will not open

• Check for clogged control line • Make sure control line is installed and open • Check for damage to the main valve diaphragm • On new installations, make sure the control line and pilot supply are properly connected

Regulator will not close

• Make sure the pilot supply is properly connected • Check restrictor for clogging • Check the main valve diaphragm for damage • Check for a broken control line

High lockup pressure with slow shutdown • Check for debris on main valve or pilot seat High lockup pressure with fast shutdown • Adjust restrictor to a higher settingNote: If you were unable to solve your proble� using this troubleshooting guide, contact your local Sales Office.
